HANDSAW- Specification of Letters Patent.

JOINTER.

Patented Feb. 26, 1907.

Application filed September 7,1906. Serial No. 333,703.

To all whom it may concern; I

Be it known that I, ALPHEUs P. HALL, a l citizen of the United States,residing at Graysville, in the county of I/Vhite and State of .Illinois,have invented certain new and useful Improvements inI-Ianclsaw-Joi11ters; and I do hereby declare the following to be afull, clear, and exact description of the inven tion, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in handsawointers, and comprises a simple and efficient device of this naturewhereby the cutting edges of teeth may be conveniently trued.

The invention comprises various details of construction and arrangementsof parts, which will be hereinafter fully described, and thenspecifically defined 1n the appended claim.

I illustrate my invention in the accompanying drawings, in which Figure1 is a perspective view showing the application of my invention. Fig. 2is a cross-sectional view through the device, showing a file heldthereto; and Fig. 3 is an enlarged detail perspective view of the invention.

Reference now being had to the details of the drawings by letter, Adesignates a jointing device which is made of a single piece of metalhaving one end bent at an angle at A and having a lateral extension Aand again bent at an angle with a downwardlyextend ing flange A forminga partial closure to receive a fileB, which rests upon the inturned lipsO. Projecting from the body portion of the jointer are the lugs D, whichextend at right angles therefrom and are adapted to contact with theface of a saw-blade E. The lower end F of the jointer is bent at anangle parallel to the lugs D and is adapted to cooperate with the lugs Dto hold the saw parallel with the body portion of the jointer.

In adjusting the device for operation a file is placed in the positionshown in the drawings and the device placed against the face of thesaw-blade, with the lugs and bottom of the device against the face ofthe saw as guides. By moving the file lengthwise back and forth, keepingthe guides in contact with the saw, -it will be noted that the teethwill be truly jointed.

By the provision of a device of this nature it will be observed that asimple and eflicient combination file-holder and gage is provided,

made, preferably, of a single piece of metal,

and by which the cutting edges of teeth may be accurately and quicklyjointed.

What I claim is A saw-jointing device made of a single piece of sheetmetal, the upper portion of which is laterally bent forming an extensionA with a downwardly-bent flange A laterally-projecting lugs C struck upfrom the opposite edges of the shank portion of the device, with theirupper surfaces in a plane coincident with the end of said flange A andadapted to hold a file, lugs D also struck up from the opposite edges ofthe device and projecting slightly in advance of the lugs O and parallelthereto, the lower end of the device being at right angles, as shown anddescribed.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
